114,488. Divided-and this application December 30, 1937, Serial No. 182,586. In Germany December 19, 1935 5 Claims.

This invention relates to toy balloons wherein air is forced into the balloon and the fabric thereof is placedunder tension and then the balloon, when released, will rise due to discharge of air through a discharge opening, this present application being a division of my application for patent, Ser. No. 114,488, flied December 5, 1936, on Toy balloons.

In toy balloons of this character, it is necessary that the aperture of the discharge nozzle be made comparatively large, as otherwise the lift will be too small. Acomparatively large nozzle aperture, however, has the disadvantage that the air within the balloon escapes too quickly so that the balloon falls to the ground in a very short time.

I have found that the lift is considerably assisted if the nozzle is made in a cup-like form, that is, is furnished with a bottom wall in which the outlet aperture is provided and if the edge of said outlet aperture is pressed inwardly so as to form a flange defining the aperture. I have also found that a hissing or whistling noise may be produced during the time when the balloon is in the air by providing a second wall disposed in spaced relation to the first named wall, this second wall being also furnished with an outlet aperture.

Three embodiments of my invention are shown I in the accompanying drawing by way of example.

In this drawing: Fig. 1 is an elevation of an inflated balloon provided with a nozzle constructed in accordance with this invention, the figures showing in dotand-dash lines the balloon when deflated.

Fig. 2 is a bottom plan view of the nozzle.

Figs. 3, 4 and 5 are vertical sections through different embodiments of the nozzle.

In the embodiment shown in Figs. 2 and 3, the balloon i 0 is shown as provided with a neck ii and the nozzle 12, which nozzle tapers downward slightly and is provided at its upper end with a bead l3 over which the neck H is forced. The nozzle is provided at its lower end with a bottom wall I! having a central aperture l5, this aperture being defined by an inwardly extending annular flange l6. By the provision of this flange l6 surrounding the outlet aperture IS, the lifting effect imparted to the balloon by the escaping air is considerably enhanced or, in other words, the balloon will stay up longer before its complete deflation than otherwise would. This flange I6 results in the contraction o'f the escaping air stream in excess of the contraction produced by a plain unflanged nozzle opening. The lift, of course, is produced by the impact of the stream (or. 46 --87i of air escaping through the nozzle against the exterior air.

If it be desired to produce a whistling or hissing noise when the air is expelled through the nozzle l2, there is provided, as shown in Fig. 4, a second bottom wall I! which is disposed within the nozzle and disposed in spaced relation to the bottom wall Hi. The bottom wall i1 is formed with a slghtly smaller outlet aperture 18 than the aperture l5 and the wall i1 is disposed in predetermined spaced relation to the bottom wall Hi.

In Fig. 5, I show another embodiment of my invention which operates in the same manner as that shown in Fig. 4 to restrict the discharge of air from the balloon and at the same time secure a whistling noise. In the form shown in Fig. 5, the nozzle I 2 has a central aperture IE, but this is not formed. with the inwardly extending flange l6. Fitted over the lower end of the nozzle is a cap l9 which is, however, provided with a central opening 20 and a flange 2i defining this opening. This cap has its bottom wall disposed in spaced relation to the wall IQ of the nozzle. This structure operates in precisely the same manner as the structure shown in Fig. 4, but has this advantage that the cap i9 may be readily removed if or when desired.

It is to be understood that while I have shown a balloon in which the nozzle provides for either inflation or deflation, yet the balloon might be provided with separate means for inflating the balloon which may be afterwards closed and then the air permitted to discharge through the deflating nozzle.

It is to be understood that no limitation is made to the specific forms of embodiment shown and that modifications of the embodiments illustrated are quite possible within the terms of the annexed claims without departing from the spirit of the invention.

What is claimed is:

1. An inflatable toy balloon having an outlet nozzle provided with a central aperture, the nozzle being formed with an inwardly extending flange defining the aperture.

2. An inflatable toy balloon having an outlet nozzle formed with a transversely extending lower end wall apertured for the discharge of air and having an inwardly extending flange defining the aperture, the nozzle having a second wall disposed in spaced relation to the flrst named wall and having a central aperture.

3. An inflatable toy balloon having an outlet nozzle, the nozzle being provided with an outer end wall having a central aperture defined by an spaced relation to the end wall of the nozzle and having a central aperture defined by an inwardly extending flange.

5, An inflatable toy balloon having an outlet nozzle formed with a discharge aperture, the nozzle having means constructed and arranged to retard the discharge of air through the aperture.
